Description

A security issue has been discovered in pixz, which can be exploited by malicious, local users to disclose 
potentially sensitive information.

The security issue is caused due to the application creating packed and unpacked files with 
umask-dependent permissions. This can be exploited to e.g. potentially disclose contents of created 
archives.

The security issue is confirmed in version 1.0.2.


Solution:
No official solution is currently available.

Provided and/or discovered by:

@maintainer(s): since the package or the affected version has never been marked as stable, we don't need to stabilize it. After the bump, please remove the affected versions from the tree.
